Hi Jonathan,

you would have to handle the WM_NCPAINT message.

This is the code we use in ScrollControl.cs to draw that area:

		private void WmNcPaint(ref Message msg)
		{
			if (this.HScroll && this.VScroll)
			{
				if(cachedRgn != IntPtr.Zero)
				{
					NativeMethods.DeleteObject(cachedRgn);
					this.cachedRgn = IntPtr.Zero;
				}

				this.cachedRgn = DrawingUtils.NCPaintHelper(this, this, ref msg);
			}

			bool themed = this is IThemedControl && XPThemes.IsThemedOS && ((IThemedControl) this).ThemesEnabled;
			if (themed && themedDrawing != null)
				themedDrawing.DrawThemedBorderColor(this, ref msg);

			base.WndProc(ref msg);
		}


		protected override void WndProc(ref Message msg)
		{
			switch (msg.Msg)
			{
				case NativeMethods.WM_NCPAINT:
					this.WmNcPaint(ref msg);
					break;

...

NCPaintHelper is a internal helper routine we use. You can look it up in the source code in Syncfusion.Shared\src\Drawing
